2. Select [Smart] > [Auto GA], the system will automatically recognize and trace the target
boundary to calculate.
The calculation result is displayed on the screen.
3. If the calculation result is not satisfactory, adjust the trace to recalculate.
a. Tap the traced contour to activate the cursor.
b. Tap to anchor the desired point on the traced contour.
c. Tap and hold the hand icon to move the cursor to the desired position, you can also tap the
arrows around the hand icon to fine-tune the cursor position.
d. Repeat steps b to c above to adjust more points if needed.
The calculation results display in real time.

1. Select a phased probe (except TEE probes) and cardiac exam mode.
2. Scan the apical 4 chamber views.
